Title: Test fixture and semiconductor testing apparatus using the same
Inventor: YUMIKURA TADAAKI
IPC: G01R31/26
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a test fixture which can enhance a transmission characteristic by a method wherein a part directly under the socket terminal of an IC socket is formed of a coplanar waveguide having a prescribed characteristic impedance and a line after that is formed of a microstrip line. SOLUTION: In a coplanar waveguide 10, a line length is short, and a frequency which displays a resonance phenomenon becomes much higher so as to be neglected for a practical use. Consequently, a transmission loss in a high region by this part is not generated. A microstrip line part 20 is a line having a comparatively thick and constant conductor width in which a comparatively long distance up to an SAM receptacle 60 connected to the outside is decided by the relative permittivity of a substrate and by the thickness of the substrate, e.g. a strip line having a conductor width of 0.5 mm. Since the conductor width is thick in the part, a transmission characteristic which is good up to a sufficiently high region can be obtained.  In a transmission line which is formed of the waveguide 10 and of the microstrip line part 20, a frequency which displays a resonance phenomenon due to the formation of a line is moved to a much higher frequency. Consequently, a transmission characteristic can be improved up to a frequency band which far exceeds 10 GHz.
